Types of Middleware

Non-Blockchain interoperability. Off-Chain & Middleware systems.

A way to facilitate interoperability between system is with off-chain or middleware systems.

-Decentralized way to exchange two assets without going through a centralized exchange.

-Real life barter system.

(work on exchange of non-like protocols)

-Can be used as a general purpose bridge between blockchains.

-Transactional activity of one blockchain can be used as an input trigger to an on-chain smart contract

-Oracles enable a wide range of cross-communication not possible in other models.

-Method for swaping assets on the same blockchain is by creating an off-chain state channel to transfer assets

-Allows different parties to trade and record ownership

-On-chain transactions are reserved for final settlement.

-Scalable and beneficial for reducing on-chain transaction cost.

-State channels can be used to exchange messages about state changes before settling on-chain

-Patented protocol that runs on top of blockchains.

-Enables cross chain messaging and atomic swaps.

-Sandbox testing environments.

-Smartcontracts can be written in one language and deployed across many blockchains at the same time. (MAPPs)

-Contracts can be quickly adjusted to work on different platforms without needing rewrite.
